Welcome. Please, Read This:
We at Crate extend our sincere “welcome” into a whole new world: a world where the
legendary performance of a musician-made Crate amplifier combines with the wonders of
digital amp modeling and effects. We bring you the only amplifier you’ll ever need: the
Crate DX-112 / DX-212. The heart and soul of sixteen different amplifiers have been cap-
tured through the miracles of digital software engineering and placed into the DX amplifier.
Not only does the amp sound like the originals, it performs like the originals, with the same
tones and character of all your favorites – from vintage British grit to today’s heavy metal –
with a wide variety in between.
Along with digital amp modeling comes sixteen digital effects, all designed to rock your
world from here to Sunday. And, you can tweak each effect to your heart’s content!
Got your own favorite effects? Not to worry – the DX amps have stereo line in and line
out jacks for use as a stereo effects loop, or for connecting to an external stereo power
amp. It’s like having your cake and eating it, too – with extra icing!
The DX amplifier is programmable and can be controlled in a number of ways, including
through the front panel keypad, with the optional Crate Foot Controller, or via MIDI.
Within the pages of this Operating Guide you will find all sorts of per-
tinent, useful and sometimes technical information which we at Crate
felt you ought to have. Please indulge us a bit and take the time to
actually read through this Guide at some point. Until then, for those
of you who just can’t wait to plug in and go, we offer you:

There you’ll find just enough information to get you started. If you run
into any situation that isn’t covered in the Quick Start section, you
might have to – guitar gods forbid – read this guide first.
We at Crate thank you for choosing the DX-112/212 Digital Guitar Amplifier!

Important Safeguards and Precautions:
All Crate products are designed for continuous safe operation, as long as common sense is used and steps are taken to help avoid cer-
tain problems. Abiding by the following rules can help prevent damage to your amplifier, yourself and others.
• The amplifier is equipped with a three-pronged AC power cord. To reduce the risk of electrical shock, NEVER remove or otherwise attempt to defeat the ground
pin of the power cord.
• Connect the amplifier ONLY to a properly grounded AC outlet of the proper voltage for your amp.
• Avoid sudden temperature extremes, rain and moisture. Also, avoid sudden and intense impact. (If the unit has been subjected to any of the preceding abus-
es, have it looked at by an authorized service center.)
• NEVER set the amplifier on a support that might give out under its weight.
• Always keep the total speaker impedance at or above the rated load.
• Unplug the amplifier before cleaning it. NEVER spray liquid cleaners onto the amplifier. Wipe it with a slightly dampened, lint-free cloth to remove dirt and film.
• Do not use the amplifier if it has sustained damage to the chassis, controls, or power cord. Refer the unit to an authorized service center for inspection.
• Amplifiers capable of producing high volume levels are also capable of inflicting permanent hearing loss or damage, if the exposure to such levels is prolonged.
Such damage is progressive and irreversible! Consider using quality hearing protection devices.

The Input Jacks:
The DX-112/212 has two input jacks – High Gain (straight) and Low Gain (padded) – to accom-
modate a wide range of pickups and playing styles. The jack you use depends on your type of
pickups and the sounds you’re after.
For example, most players will plug their guitars into the High Gain jack. These players include those
with “normal output” pickups and some players with “hot” pickups who are looking for some
added distortion.
Some players will choose the Low Gain jack. These players are mostly those with “hot”/active
pickups who want a cleaner sound, with more headroom for the Gain control.
When nothing is plugged into either jack, the DX-112/212 mutes its internal speaker(s).
The Stereo Line Out/In Jacks:
The DX-112/212 has a Stereo Line In and Line Out jack (rear panel), for use as a stereo effects
loop, or to send a preamplified signal to an external stereo power amp.
To use an effects loop, connect the Line Out jack to the input of the effects device, then connect
the output of the device to the Line In jack.
To send a preamplified signal, connect a stereo signal cable from the Line Out jack to the input of
the stereo power amplifier.
The jacks are wired as follows: TIP = left channel, RING = right channel, SLEEVE = ground.
The Line Out jack signal is post master, post eq, and post effects.
•If you want to connect a DX-112 to
another guitar amplifier for stereo
sound, you’ll need to make a custom
patch cable like the one shown to the
right. Use this cable to connect your
DX-112 Line Out jack to the Line In
jack of the second guitar amp AND
the DX-112 Line In jack.

UUssiinngg aa MMIIDDII FFoooottsswwiittcchh::
You can store and recall a total of 100 presets when using a MIDI footswitch. These presets are
accessed by MIDI program numbers 0 through 99. (Also, see the MIDI Implementation Chart,
Appendix B, page 45.)
WARNING: The MIDI In/Crate Foot Controller button must be in the OUT position
for MIDI operation. (The IN position applies power to the Crate Foot Controller
which could cause damage to another type of MIDI footswitch.)
UUssiinngg tthhee CCrraattee FFoooott CCoonnttrroolllleerr::
The optional Crate Foot Controller (model DX-FC) lets you store and recall a total of 100 presets and
allows foot control of the tap tempo function. The controller gets its power straight from the amplifier,
so no external power source or batteries are needed!
Plug the connecting cable into the MIDI In/Foot Switch jack and set the MIDI In/Crate Foot Controller
button to the IN (foot controller) position. This applies the power needed for the Crate Foot Controller.
(See the Foot Controller’s User’s Guide for more complete information-when you get one!)
TThhee MMIIDDII TThhrruu//OOuutt JJaacckk::
The MIDI Out/Thru jack lets you control other MIDI devices with the Foot Controller. Connect this
jack to the MIDI In jack of the device you wish to control.
The MIDI Thru works with either a standard MIDI input (footswitch) or with the Crate Foot Controller
plugged into the MIDI In jack, since the Crate Foot Controller sends standard MIDI messages.
TThhee SStteerreeoo HHeeaaddpphhoonneess JJaacckk::
Plug a pair of stereo headphones into this jack, for private listening. The internal speaker(s) is (are)
disconnected when headphones are used. The headphones signal is speaker compensated for a
realistic sound even without a guitar speaker cabinet. Since this amp can play LOUD, be careful
when using headphones – prolonged exposure to those high dB levels can wreak havoc on your
eardrums!
• The Headphones Jack can also be used as a stereo direct out for recording.
DX-112/212 Digital Guitar Amplifier
11
The DX-112/212 is actually 16 different amplifiers in one! The software inside the amplifier con-
vinces the signal that it’s going through the electronic components of the original amplifier, giving it
all of the characteristics of that amp! (More or less – it’s really a lot more technical than that, but
you get the picture. For a slightly more technical description, see Appendix A on page 43.)
Use the amp selector knob to choose which amp model you want. The chart on the following
page lists the name we gave the amp model, the “make and model” of the amp we emulated, and
a brief description of the original amp.

AAMMPP MMOODDEELLSS
Model Name Modeled After the... Brief Description
Top Mount Vox AC 30 Bright with a great clean sound at low gain, distorts smoothly at high gain
settings – an early 60’s amp with lots of 2nd and 3rd order harmonics,
favored by the Beatles for the rhythm and lead tracks in their early days
High Power Hi Watt DR An early 60’s “upmarket” alternative to the popular Marshall amp – loud-
er and cleaner than most
Studio Tweed Fender Deluxe 5E3 The sound from which Rock ‘n’ Roll was born – Fender’s early 50’s claim
to fame
Black Face Fender Deluxe Reverb AA763 The classic tube amp – one of the first amps with reverb, a mid-60’s sta-
ple to the rock and roll diet (considered by some to be one of the best
amps ever made)
Large Tweed Fender Bassman 5F6-A Originally designed for bass, favored by guitarists for its big sound – a late
50’s classic
60s Era UK Marshall 1959 The renowned “brown sound” – a softer, smoother Marshall than the
more modern creations
70s Era UK Marshall JCM 800 The sound of ROCK! – loud and powerful with a definitive edge
Fuzzbox Dallas-Arbiter Fuzz Face Jimi would be proud – the classic stomp box distortion of his day
Tube Rectifier Mesa-Boogie Dual Rectifier Barre chord Heaven – the beginning of the modern high-gain amp era
Calif Mod Mesa-Boogie Mark IIC+ Tons of overdrive and sustain; the sound of Santana! – the hot-rodded
powerhouse Simul-Class amplifier
Ampeg VL Ampeg VL-501 A hot-rodded Marshall-style amp – powerful, lots of distortion and multi-
ple gain stages
Flexwave Crate GX-140C The massively overdriven, solid state Crate sound preferred by Metal-
Heads everywhere – a solid-state competitor for most classic tube amps
due to Crate’s proprietary FlexWave circuitry
Vintage Club Crate VC-60 A unique combination of both modern high-gain and classic tube amps
– bringing back the “vintage” sound of the early days of rock
Blue Voodoo Crate BV-60 Awesome modern high-gain tone – smooth, clean, and powerful
Acoustic Boss AC-1 Acoustic Simulator Makes your electric guitar sound like an acoustic
Clean Crate GX-140C Clean Jazz sound – just enough of a an edge to get your message across
All-important, legal, “cover-our-rear-ends” blurb!

AAMMPP MMOODDEELLSS
Each DX-112/212 amp model has its own specifications and placement in the signal chain for its
Gain, Bass, Mid, and Treble. (In other words, the controls affect the signal the same in the amp
model as they do on the original amplifier.)
Use the Preset Parameter controls (Gain, Bass, Mid, Treble, Channel Level) to change the gain, eq
and volume of the selected amp model. The chart on the following page lists the model name and
the specifications/placement for the Drive and EQ controls.
TIP! When using the Acoustic or Clean amp models, set the Channel Level to maximum
and use the Gain control for your volume level.
